EVQ4475-E-R-00A 7-36V, 2.5A Frequency Selectable Step-Down Converter Evaluation Board QFN-25

The MPS EVQ4475-E-R-00A is an evaluation board built around the MPQ4475-E for bench characterisation of the device in its intended topology. It operates from a 7 V to 36 V input, is rated for 2.5 A and switches at 150 kHz. The board carries the device in its QFN-25 package.

The EVQ4475-E-R-00A Evaluation Board is designed to demonstrate the capabilities of MPS' MPQ4475-E.

Design Notes

The board ships in a default configuration; check the jumper and resistor options against the user guide before applying power.
Respect the input terminal rating — most faults on evaluation boards come from an supply above the marked limit.
Test points on the switching node and output are for a short-ground probe, not for a long oscilloscope lead.
Where a GUI is supported, connect the dongle before power-up so the device enumerates on the I²C bus.
